ASTM F1197-19

Standard Specification for Sliding Watertight Door Control Systems

ABSTRACT
This specification covers the design, manufacture, and testing of controls and operating mechanisms for use with sliding watertight doors. Sliding watertight door control systems shall be classified as manual and power. Manual door control system requires the operator to apply a continuous cyclic force to the door controller to cause the operating mechanism to function. This type of control system has two kinds: mechanical system and hydraulic system. The power door control system requires only that the operator exert a minimal physical force to cause the operating mechanism to function. This type of control system has three kinds: electric system, hydraulic system, and electrohydraulic system. All sliding watertight doors shall be provided with a means of local and remote manual operation. Door control systems, both manual and power, shall be designed to open and close doors against a 15° list. In addition, the operating mechanisms shall be designed to close the door against a static head equivalent to a certain water height at least above the sill on the centerline of the door.
SCOPE
1.1 This specification covers the design, manufacture, and testing of controls and operating mechanisms for use with sliding watertight doors meeting the requirements of Specification F1196.  
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview

ASTM F1197-19: Standard Specification for Sliding Watertight Door Control Systems is a key industry standard developed by ASTM International for the design, manufacture, and testing of control systems and operating mechanisms used in sliding watertight doors. These systems are critical to marine safety, ensuring watertight integrity and operability of doors in vessels such as ships, offshore installations, and other maritime environments.

This specification details requirements for both manual and power-operated sliding watertight door controls, addressing aspects such as safety, reliability, remote operation, and environmental resilience. The document also integrates internationally recognized standardization principles and incorporates references to related ASTM, IEEE, SAE, ASME, and NEMA standards.

Key Topics

• Types of Control Systems
  • Manual Systems: Require continuous application of force by the operator, including both mechanical and hydraulic variants.
  • Power Systems: Require minimal operator input and include electric, hydraulic, and electrohydraulic options.
• Operational Requirements
  • All doors must be operable locally and remotely, both manually and (where applicable) by power.
  • Control systems are required to function when the vessel is listed to 15°, and to close doors against a specified water pressure.
  • Safety features such as alarms, indicators, and fail-safe operation are mandatory.
• Design and Construction
  • Specifies material quality, prohibiting untested cast iron components.
  • Details about component durability, hydraulic safety factors, sealing, and resistance to marine environmental conditions.
• Testing and Certification
  • Mandates prototype and operational testing under shop conditions, including inclination and pressure tests.
  • Manufacturers must certify compliance with all design, testing, and operational requirements.

Applications

ASTM F1197-19 is widely applied in the shipbuilding and marine engineering industries, especially for vessels and platforms requiring stringent watertight compartmentalization. Practical uses include:

• Commercial and Naval Ships
  • Ensuring safe compartmentalization and quick response in emergencies.
  • Essential for compliance with international marine safety regulations.
• Offshore Structures
  • Utilized in oil rigs and floating installations for watertight integrity.
• Retrofit and Maintenance Projects
  • Guides updates or replacements of sliding watertight door mechanisms to match current safety and reliability standards.
• Inspections and Certifications
  • Used as a baseline for inspection, maintenance, and certification of watertight door systems by regulators and classification societies.

Related Standards

ASTM F1197-19 references several other important standards to ensure comprehensive coverage and interoperability:

• ASTM F1196: Specification for Sliding Watertight Door Assemblies
• IEEE 45: Recommended Practice for Electrical Installations on Shipboard
• IEEE 100: Standard Dictionary of Electrical and Electronic Terms
• SAE J524/J525: Seamless and Welded Low Carbon Steel Tubing
• MIL-DTL-901: Shock Testing for Shipboard Machinery and Equipment
• ASME Code, Section VIII, Division 1: Boiler and Pressure Vessel Code, Pressure Vessels
• NEMA IS1.1: Enclosures for Industrial Controls and Systems

Industry professionals, designers, and inspectors rely on ASTM F1197-19 to ensure sliding watertight door control systems provide robust safety, reliable operation, and compliance with critical maritime regulations. Using this standard helps enhance safety, protect assets, and streamline approval procedures in marine environments.
